Core Utilities

Shared infrastructure used across all feature modules, located in lib/core/.

Connectivity

• postJson<T> / sendPostRequest — generic HTTP POST helpers that serialize any model with a toJson() method
• Supports custom headers and configurable timeout (default 90 seconds)
• HttpOverrides — custom SSL/certificate handling for internal network connections
• SignalR integration (signalr_netcore) for real-time push from the backend

Idle Detection

• LmpIdleDetector / LmpIdleDetectorWrapper — wraps any screen to monitor user inactivity
• IdleDetectorProvider — Riverpod provider exposing idle state
• IdleCountdownWidget — shows a countdown before auto-logout
• IdleAlertListener — listens for idle events and triggers the logout flow

Image Helpers

• LMPImageUpload — handles image picking (image_picker) and compression (flutter_image_compress) before upload
• WindowsCameraDelegate / WindowsCameraPickerDelegate — platform-specific camera delegate for Windows desktop builds

Device Information

• DeviceInformation / DeviceInformationModel — collects device ID, platform, OS version, and network info (device_info_plus, network_info_plus)

Models

Common request/response models used across features:

• ApiResult, BaseResult, ApiReturnString — standardized API response wrappers
• ApiRequestBase — base class for all outgoing API request models
• PaginatedState<T> — generic pagination state for list providers
